Product Description



*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***




 ** Click HERE for the NEW GruvenParts Installation Video **

** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 2 Options Are Now Available ***

Note that if you chose Option 2, you will either need to send in your unit for repair directly, or wait approximately 2 months for us to get a unit to repair.  These are becoming hard to find and people arent returning their cores as often anymore for some reason.  We can usually repair sent in units same day to minimize down time as you cant install the mirror without the drive unit in place.

Option 1: 

Buy strengthened steel gears machined integral to the main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  

Option 2:

Buy a rebuilt complete motor drive unit with new hi-torque motor + steel integral gear already installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units we have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.  We are currently on a 2 Month Back Order Unless You Can Send In Your Unit to be Rebuilt


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened STEEL gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened integral spiral spur/worm gear shaft made from high strength steel to eliminate the fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can chose to buy the gear/motor combo for one or both sides or you can buy complete drive units which are rebuilt and already have the new metal gears and hi torque motor installed in them.  

We have thoroughly tested our redesigned integral gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.


** Application ** 

Gears and Motors Fit Both Passenger and Drivers Side Power Folding Mirrors.  

All 2007-2014 GM SUV's With Power Folding Non-Tow Mirrors Including Acadia, Traverse, Enclave, Escalade, Tahoe, Suburban, Yukon, and Denali. 

All 2007-Present GM Pick Up Trucks Including all Silverado and Sierra with Non-Towing Power Fold Mirrors -- please note the 2014+ pick up trucks used different plastics on the frame, so disassembly of the mirror frame doesnt match the DIY.  The lower half of the drive unit with all the gears inside IS the same as the previous generation.

This includes (but not limited to) the following mirror assembly part numbers :

25-83-12-36 (25831236), 25-77-98-49 (25779849)

This list of part numbers will continually grow as we build the interchange list.  This is in no way complete, as most GM trucks made from 2007-2014 with power folding mirrors will use this gear.  If your power folding mirror looks like the mirror shown in the DIY, this gear will fit your vehicle.


... We also have many more products for GM, including the towing mirror gears, 2015-Present SUV non-towing mirror gears, door lock motors, door handle inserts !  Check out the GM section of our website!

  1. Worked Perfectly 5 Star Review

    Posted by on 20th Aug 2022

    I bought the rebuilt motor assembly for my 2012 GMC Sierra SLT Crew Cab. I keep my truck in the garage and it won't fit unless I fold the mirrors in, so use that power folding feature every day. I followed the instructions on the YouTube video which was very helpful and was able to complete the replacement of the motor assembly in about 1-1/2 hours. It works perfectly. Cosmetically the rebuilt one has a little surface rust whereas my old one looks brand new but doesn't work anymore. Since it's not visible once everything is back together, I'm happy to have one that works even if it doesn't look new.

  2. they work great 5 Star Review

    They work great, I bought both motors and gears

  3. Works exactly as it should! 5 Star Review

    Posted by on 5th Aug 2022

    Great product. The gear broke on my mirror. My motor was weak and wouldn't work. I put this gear and motor in and it works fantastic. I bought two for $99 because I'm sure the other side will go out at some point. Worth the money.

    The replacement parts work great but I am still waiting on my credit for the cores that were sent back

  5. 2012 GMC Folding Mirror 5 Star Review

    Posted by on 20th Jul 2022

    The parts that Gruven have designed are better than OEM by far. The video for the installation was top notch, it made the process easy. I know that it is just a matter of time before I once again call on Gruven as I fold and unfold my mirrors every time I leave and reenter the garage.

  6. Great guys... 5 Star Review

    Exactly what I needed!

  8. Worked Out Great!! 5 Star Review

    Posted by on 17th Jul 2022

    I completed installing the spur gear replacement kit for my 2007 Silverado LTZ power mirrors. EVERYTHING WORKED TO THE "T". I simply followed the video instructions. They worked great and with a little time I saved money and upgraded to a more durable and reliable power fold mirror.

    I do have a suggestion. Would like to see a more prompt response for questions or a phone call if really needed.

    I will be ordering other gear replacement parts for my trucks.

    Thank you

  9. Great fix for an 09 Silverado 4 Star Review

    Posted by on 17th Jul 2022

    I purchased 2 of these motor and spur gear sets to replace the broken spur gears in my factory folding mirrors on my 09 Silverado. My factory folding mirrors had broken within a month after purchasing the truck used in 2018. Installation took 3-4 hours between the 2 mirrors, and was fairly straight forward, although I would highly recommend watching their installation video and referencing their PDF instructions that are available on their website . After finishing assembly I was extremely pleased with the performance, the mirrors fold in and out very quickly, much quicker than they did when I first purchased the truck and still had working mirrors.

    The only complaint I have is that I did not receive a Brass spur gear as advertised, but instead received a solid stainless steel gear. I did not see this advertised anywhere on the listing before ordering this kit. Being stainless steel it should last longer than the advertised brass spur gear and will likely not cause any problems, although I do worry about the tiny brass worm gear on the motor being worn out quicker than it would if both gears were made of brass, but at least the motors and gears have a lifetime warranty if I ever need it.

    Overall I am very pleased with this kit and how well it has functioned so far. I would definitely recommend these to a friend if they were looking to fix their broken power folding mirrors

    -- response from GruvenParts --

    Thanks for the review. We cannot make both gears from the same material so this design actually works out better with 1 being harder than the other so they wont gall. The brass motor gears is still very strong, you would never wear it out in 1,000 years.


  10. Direct replacement 5 Star Review

    Posted by on 30th Jun 2022

    These are a great fix for GM full size truck mirrors once they get tired and stop obeying the fold button :) . I used these for both mirrors on my 09 Suburban and they are a direct OEM fit yet higher quality. As a former GM technician, I can say the pdf instructions and video tutorials are spot on if you need them for reference. They took me about an hour per side to swap out, so they are easy enough to knock out over the weekend if you take your time. Much less expensive than unnecessarily replacing both mirror housings.
